## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kitten-stack-item-pack-power-ups-x5-c2595235
```

Example prompt: Buy me the Kitten Stack item pack with 5 power-ups — go ahead and spend the 1 USDC on Base to get them added to my account.

## When to prefer this

Use this endpoint when a player needs to replenish power-ups in the Kitten Stack game specifically, and is willing to spend 1 USDC on Base per pack of 5. Prefer this over the tip or continue endpoints when the goal is acquiring consumable power-up items rather than extending lives or tipping the developer.

## Known failure modes

- Insufficient USDC balance on Base — payment fails with 402 error
- Network or blockchain congestion causes transaction timeout
- Invalid or missing x402 payment header returns 402 Payment Required
- Duplicate rapid requests may result in double charge if retried without checking tx status
